Title: Method and instrument for measuring molten metal surface level in continuous casting mold
Inventor: OKA MASAHIKO
IPC: B22D11/16
Filed: 1993-07-27
Abstract: PURPOSE:To provide a method and an instrument for measuring the molten metal surface level in a continuous casting mold for which the influence caused by oscillation can be removed without causing the phase delay. CONSTITUTION:A computing element 17 estimates frequency in the oscillation component by the oscillation based on stroke s0 and cycle c0 set in an oscillation cylinder 7 and casting velocity Vc obtained from a speed meter 8 provided in a pinch roll 31. On the other hand, a comparison computing element 13 matches the molten metal surface level y1 obtained from a low low-pass filter 12 with the molten metal surface level y0 obtained from a differential amplifier 19 to send the differential signal between both levels to the computing element 17. The computing element 17 corrects the estimated frequency (f) based on the differential signal. A band pass filter 18 extracts a signal in a prescribed frequency band containing the corrected frequency f0 from the level signal to send it to the differential amplifier 19 as the oscillation component. Thus, the differential amplifier 19 outputs the molten metal surface level y0 by reducing the oscillation component from the level signal removed with the noise of high frequency by a noise removing filter 11.

Title: Semiconductor device and its manufacture
Inventor: UEDA TAKEHIRO
IPC: H01L27/092
Filed: 1998-06-30
Abstract: PROBLEM TO BE SOLVED: To reduce the junction capacitance of a complementary MIS semiconductor and the number of photolithographic processes at the forming of the transistor in a semiconductor substrate. SOLUTION: When a complementary MOS transistor is formed in a P-type semiconductor substrate 1, the need for implanting the ion of an N-type impurity deep into a gate electrode 9 at a high concentration is eliminated by introducing in advance the N-type impurity over the full film thicknesses of gate electrodes 8 and 9. Therefore, the junction capacitance of the MOS transistor can be reduced, because a source region and a drain region having required concentrations and depths can be formed in the N-type MOS transistor region of the substrate 1. Since the N-type impurity is injected at a sufficiently low concentration, the polarity of the electrodes 8 and 9 can be inverted easily, when a P-type impurity is injected into the electrodes 8 and 9 at the conventional concentrations.

Title: Sequential re-construction method for bit plane
Inventor: POORU UIRIAMU JIYOONZU
IPC: G06F3/153
Filed: 1993-07-28
Abstract: PURPOSE: To improve the visibility of a restructured image. CONSTITUTION: When (m) is the total number of received bits, a bit combination logic block 12 receives >=1 (k)-bit representation and received bits which are already received and restored and combines them together to generate an (m)-bit sequence. An output value generation logic block 40 combines an (n-m)-bit sequence with this (m)-bit sequence to generate an (n)-bit output value. An output frame buffer buffers the above mentioned (n)-bit output value. A precedent-bit recovery logic block 20 recovers all (m) bits which are received precedently from the buffered (n)-bit output value. The (m) bits are supplied to the bit combination logic block 12. Those steps are repeated until desired bit depth is obtained and the output from the precedent bit recovery logic block 20 is displayed on an (n)-bit display device 10, so that a restructured image can be seen.

Title: Press cooling mechanism in rotary molding system
Inventor: ITO KAZUHIKO
IPC: B29C45/56
Filed: 1988-07-28
Abstract: PURPOSE:To prevent the occurrence of an oil mist or the like by press-molding the mold resin within a cavity in such a manner that as a press unit is actuated against the spring force of a spring member, a second compression rod presses a first compression rod, subsequently, the first compression rod presses a movable piece. CONSTITUTION:A first temperature control plate 34 is moved downwards in actuating a press cylinder 56. Since refrigerant flows in a bore 41, the heat of a mold 12, in which a first temperature plate 34 is put into contact with the surface of the mold 12, moves upwards communicating the first temperature plate 34. The second compression rod 47 renders the first compression rod 10 to be moved upwards relatively to the mold 12, thereby, a movable piece 9 slides upwards. And, when the lower surface of the second temperature control plate 35 comes into contact with the upper surface of a base table 32, the contour line around the surface forming the cavity of the movable piece 9 comes to be a condition wherein it coincides with the inside contour line of upper surface of a stationary piece 8. In this condition, namely, the condition wherein the resin inner pressure within the cavity has been raised in a predetermined quantity, the cold curing of the resin can be performed.
